ABSTRACT:
An athletic shoe of reduced weight is described employing low density, closed cell, synthetic plastic foam for an intermediate sole layer and/or heel lift sole layer between a harder outer sole layer and the shoe upper. The foam is a polyethylene or ethylene vinyl acetate foam having a density not substantially less than 5 pounds per cubic foot, preferably at least 7 pounds per cubic foot. A lateral extending heel stabilizer plate of solid plastic material or a heel lift layer having a relatively hard outer border portion may be added to improve lateral stability.
